As regular readers of this blog will recall, I asked a question of the Mars Curiosity team about imaging technologies during the post-landing press conference at NASA JPL a few days ago.
Related: Digital Photography Review now has an interview with the Mars rover camera project manager. Above, the 34mm (115mm equiv.) Mastcam from the Curiosity rover. This was developed by Mike Ravine and his team at Malin Space Science Systems, a contractor for NASA. Ravine explains how they developed the 2MP main imaging cameras used to transmit those breathtaking images back from Mars.
The slow data rates available for broadcasting images back to Earth and the team's familiarity with that family of sensors played a part, says [Ravine], but the biggest factor was the specifications being fixed as far back as 2004. Multi-shot panoramas will see the cameras deliver high-res images, he explains, but not the 3D movies Hollywood director James Cameron had wanted.
'There's a popular belief that projects like this are going to be very advanced but there are things that mitigate against that. These designs were proposed in 2004, and you don't get to propose one specification and then go off and develop something else. 2MP with 8GB of flash [memory] didn't sound too bad in 2004. But it doesn't compare well to what you get in an iPhone today.'

SpaceX and Space Adventures have partnered to offer space tourists a trip to orbit on the SpaceX Crew Dragon space capsule. They expect the first flight to launch in late 2021 or early 2022. Around $50 million will get you a seat. From Spaceflight Now: The mission would not dock with the space station, but […]
Thirty years ago today, the Voyager 1 spaceprobe had completed its ncounters with the outer planets and was careening out of our solar system. The time came to shut off the probes’ cameras to preserve power and memory for the other onboard scientific instruments. But before engineers flipped the switch, one last photo opportunity was […]
While scientists have studied Moon rocks for 50 years, researchers have for the first time conducted deep analysis on a single grain of lunar dust, atom by atom. Using a common materials science technique called atom probe tomography that’s not widely used by geologists, the Chicago Field Museum’s Jennika Greer and colleagues probed the grain […]
In the early days of the web, everyone wanted a .com domain for their site. As a result, all the good ones got snapped up. But .com no longer has the cachet it once did. In fact, many new businesses and individuals are opting for other top-level domain extensions. One of the most memorable is […]
As you shiver your way through February, you’re probably thinking about paying your heating bill. But in just a few short months, the summer sun is going to come calling — and the fear of pulling that energy bill out of your mailbox will start becoming very, very real. Air conditioning accounts for about an […]
Despite legalization in 11 states and decriminalization in 15 more, marijuana-based products are still an often tough sell with many Americans. While the psychoactive THC portion of the plant remains controversial, the medicinal impact of the non-altering component of cannibis, CBD, is widely hailed. Many portions of those claims still await medical verification, but for […]
